Regarding hot rolling of steel, the quality of the rolled metal surfaces depends to a large extent on effective descaling. In order to avoid surface damage, iron oxide scale layers are therefore removed from the hot steel surface by high-pressure water spraying prior to the actual hot rolling process.

The stable and reliable rolling of thin strip in the finishing mill of linked casting and rolling processes such as Arvedi ESP (endless strip production) and Compact Strip Production (CSP), or in conventional hot-strip mills, has increased the requirements for precise mass-flow and thickness control. As an initial

Current neural modelling applications for predictive control of strip rolling mills include prediction of the temperature of the rolling stock, prediction of the spread in the roughing mill and the finishing mill, prediction of the rolling forces and others. For more than two years electric arc furnaces are controlled by neural networks.

One-Pass Hot Rolled Strip - One-pass strip is gauge-corrected for closer thickness tolerances on a cold rolling mill. This option is not annealed and lower in cost. With a ferritic, hot rolled structure, one-pass has harder, more variable physical properties appropriate for less demanding applications where bends and forming are less severe.

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Two-High: Generally, a 2-HI mill is used for hot or cold breakdown and finishing of bar, sheet or strip. A wide range of sizes with separating force capacities from 10,000 lbs. (4.53 MT) to over 3,000,000 lbs. (1360 MT) are available. Three …

TMEIC Supplies Superior Control Systems for Hot Rolling Mills Hot rolling mills roll heated steel, stainless, and aluminum slabs to make hot strip with a thickness of a few millimeters to over ten millimeters. Hot coils are shipped as they are, or moved to another operation and processed to cold rolled sheet, coated steel sheet, or steel pipe.

Danieli Wean United. The world's first 4-high Continuous Hot Strip Steel Rolling Mill, which made it possible for width and gauge ratios to be increased from 250:1 to 500:1 up to 1000:1.

This paper discusses three case studies of application of ML in rolling mills of steel plants. ... development of a cobble prediction system in a hot strip mill using statistical method and ...

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

Hot rolling. This process stretches a slab into a strip. The slab is reheated to approximately 1250°C and rolled in hot conditions. The resultant strip steel is wound into a roll like toilet paper (hot coil). Chains for lifting; Toughrollers; Conveyor chains for conveying semi-finished products

Rolling of Steel in a Modern Long Product Rolling Mill. Long product is a common name for (i) reinforcement steel bars, (ii) shaped steel bar products such as rounds, flats, squares, and hexagon etc., (iii) sectional products such as angles (equal and unequal), channels, beams, tees, and special profiles etc., and (iv) wire rods.

Flat Rolling •Roll Force: F= LwY avg •Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value

The main users of scrapped irons are the local steel re-rolling mills producing MS rods, MS bars, angles and steel sheets for domestic market. A furnace is an equipment used to melt metals for casting or to heat materials to change their shape (e.g. rolling, forging) or …

As a hot strip of steel passes through a series of rolling stands that reduce and alter its shape and length, the supporting bearings must endure relentless punishment in the form of high heat, heavy and impact loads, variable speeds with rapid accelerations, and the constant presence of cooling water. All while running with accuracy to meet increasingly stringent standards for …

5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.
